Now that the NFL's unrestricted free-agent negotiating window is open, a source close to Bush told The Miami Herald that three teams -- but not the Dolphins -- have been talking to agent Joel Segal. The money bandied about in those early discussions is labeled as "significant."

UPDATE:USA Today reported Saturday the Arizona Cardinals have contacted Bush's agent, according to a source with knowledge of the communication. That's no surprise, as new coach Bruce Arians looks to upgrade a backfield that has struggled to stay healthy in recent seasons.
